WATER AND GAS SEPARA'IOR Filed May 10, 1941 (7472 22061? raam INVENTOR ATTORNEYS Patented July 21, 1942 UlTED STATES P a f a This invention relates to a water and gas separator and has for an object to provide a device of this character having oppositely inclined bafiies through which gas will be caused to travel a circuitous path to separate water therefrom so that a dry gas will pass out of the separator.

A further object is to provide a float controlled valve and water discharge pipe through which the accumulated water in the bottom of the separator is discharged by as pressure whenever the water level reaches the height of the float.

A further object is to provide a device of this character which will be formed of a few strong, simple and durable parts, which will be inexpensive to manufacture, and which will not easily get out of order.

With the above and other objects in view, the invention consists of certain novel details of construction and combinations of parts hereinafter fully described and claimed, it being understood that various modifications may be resorted to within the scope of the appended claim without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawing forming a part of this specification:

Figure 1 is a longitudinal sectional view of a water and gas separator constructed in accordance with the invention.

Figure 2 is a longitudinal sectional view of the water and gas separator taken in a plane at a right angle to Figure 1 with the float valve and water discharge pipe removed.

Figure 3 is a cross sectional view taken on the line 3--3 of Figure 1 showing the staggered arrangement of the gas ports in the baffles.

Figure 4 is a cross sectional view taken on the line d l of Figure 1 showing the float controlled valve and supporting bracket therefor in top plan.

Figure 5 is a detail plan View showing the angular brackets for securing the partition to the wall of the separator.

Figure 6 is a perspective view of the removable partition and baflles assembled with the angular brackets.

Referring now to the drawing in which like characters of reference designate similar parts in the various views, Ill designates an upright cylindrical casing having flanged upper and lower ends to which are bolted respectively a cap plate II and a base plate l2, there being respective gaskets l3 and I4 disposed between the plates and the flanges of the casing to make the casing gas and liquid tight. A gas inlet pipe I5 enters the casing near the top thereof and diametrically opposite the inlet pipe a gas outlet pipe l6 enters the casing.

A partition I? is disposed centrally in the casing and extends downwardly from the cap plate II to a point below the median transverse diameter of the casing. The partition is removably secured at the longitudinal edges between angular brackets I8, through the medium of bolts 19 disposed at the top of the partition. The brackets are welded or otherwise secured to the inner wall of the casing. Removal of the bolts l9 permits removal of the partition together with the baffles 20 carried thereby for inspection and repairs.

The baffles 20 are in the nature of circular disks which are alternately inclined opposite to each other, see Figure 2, and are spaced'unifofm- 1y apart. Each baffle snugly fits within the casing and is provided at one point in its circumference with a slot 2| to receive the radially disposed flanges of a pair of angular brackets 3, see Figure 5, and diametrically opposite the slot is provided with a semi-circular gas port 22. Each baflle may be assembled with the partition I! by cutting the baffle in two half semi-circular sections and securing the sections to opposite faces of the partition by welding or other preferred means. The gas ports 22 are staggered relative to each other so that no two gas ports align with each other and consequently the gas must travel a circuitous path downward from the inlet pipe I5, against the baffles 20, through the gas ports 22 on one side of the partition underneath the bottom of the partition, and then upwardly upon the opposite side of the partition through the gas ports 22 and across the bafiles to the outlet pipe l6, as indicated by arrowheads in Figures 1 and 2. During travel in this circuitous path, the gas'will be scrubbed free of water, oil or other liquid, and the liquid is percipitated and accumulated in the bottom of the casing, so that while a Wet gas enters the casing, a dry gas will leave the casing.

For purging the casing of accumulated water or other liquid, 2. liquid discharge pipe 23 extends upwardly exteriorly of the casing and is provided at the lower end with a lateral extension 24 which enters the casing and is equipped with a conventional valve 25. A downwardly extending intake nozzle 26 is connected to the valve casing and opens near the bottom plate l2 so as to always be below any water level in the casing,

An inverted cup shaped float 2! is secured to an angular float stem 28 which extends through a channel bracket 29 which extends transversely of the casing below the partition and is secured at the ends to the inner surface of the casing, in any preferred manner. The float stem 28 is pivotally connected to one upright flange of the bracket, as shown at 38, while the stem extends through a guide opening 3| in the other upright flange of the bracket. Intermediate the flanges of the bracket, the float stem is pivotally secured, as shown at 32, to the stem 33 of the valve 25.

The float 21 is so disposed that when the liquid level in the casing I0 rises to the level of the extension 24 of the discharge pipe 23, the float will open the valve 25. Thereupon gas pressure in the casing IE] will immediately blow out the accumulated liquid through the open valve and discharge pipe 23 and thus permit the float to fall and close the valve until enough liquid accumulates in the casing to again require purging.

From the above description it is thought that the construction and operation of the invention will be fully understood without further explanation. 3

What is claimed is:

A liquid and gas separator comprising, an upright casing, an inlet pipe entering the casing near the top thereof, an outlet pipe entering the casing near the top thereof, a vertically disposed partition in the casing dividing the casing into two compartments between the outlet and the inlet pipes, said partition terminating short of the bottom of the casing, a plurality of alternately oppositely inclined bafiles carried by the partition and extending to the inner surface of the casing, said bafiles having respective ports staggered relatively to each other and disposed adjacent to the inner surface of the casing for causing liquid ladened gas to travel a circuitous path down through one compartment underneath the bottom of the partition and up through the other compartment for precipitating liquid from the gas to the bottom of the casing, angular brackets secured to the inner surface of the casing, and bolts removably securing the partition to the angular brackets to permit the partition and baffles carried thereby to be Withdrawn as a unit from the casing for inspection and repairs.
